Were you using Healkili's Ret Helper? Cause all you have to do is go into the code or whatever to the part where the spell ID for Blade of Virtue is and just replace it with the one for Blade of Justice since it's the same ability now and it'll work fine as before.
I can't speak for Hekili (it seems to have a great following) or for whatever specific WA string you were using before, but I can 100% tell you the Tell Me When rotational addon being updated by Chesder has been a GREAT tool and is relatively easy to setup/customize.
